To prevent vulve sea 3 frein being disengaged in nnuv wiiv, iiidenturesll are inside in easing helow und upon which vulve-seat nicniher 3rests. Directly bene-ith these indeiitures und adjacent its lower end,the CaS- inu' is provided with a tzinsversel here l2 in which is placedthe ends of it wire spring, the spring i3, so formed iis to `followaround the interior of easing 7 und rests upon :i small ledge l-/l :ithuso oi casing. f

ln the upper end or' the easing is pla-ced the glass guur-d 10, the twobeing securely i l'nsiened together liv impression of the inetil i'using into the nzniiilin' `groove 16. The ghiss 2g'iiiiril is providedwith a series of longitudiiiiil :und annular grooves so arranged as toforni stiip'gered eonnnunicetion with the grooves in the casing.

For trimsportiitioii,- storture' und sealing purposes; the hottie iieekis proportioned'to extend upwiirdlv heyend the top of the bottie easing;und guard for the reception of 9. cork or other stopper. v

lt will he understood that when the bottle is iii zin upright position,the viilvecap 4 will he s urteil on the valve seat 3 to preventeviii'ioriiiion of contents sind also to prevent reiilling the bottles;hut when the bottle is inverted the yelve-esip 4 together with the solidhull o will i;riivitzite to the upper end of l The eosinoing :ieontinuous oi'iening through the valveseiit,tliegriooves in the easingandthe grooves in the top guard 1U. for the liquid to pass from thehottie outward through the neck.

l liiving thus` described the invention, what eliiiiiied is,

4. A bottle closure, comprising a casing, a valve seat attached to thelower end thereof, a valve in the casing over said seat, a guard havinga circumferential groove and staggered gs on its periphery, said guardwithin the casing and' the latterhaving a circumferential bead enteringthe circumferential groove 1n the guard and securing the latter 1n placewithin the casing.

5. The combination with a bottle having the bore of its neck of lessdiameter in its `lower than in its upper portion, of a casing locatedwithin the neck of the bottle and conforming to the interiorconformationthereof, a'valve seat attached to the lower end of the contracted lowerportion of the easing, a valve movable within said contracted portion ofthe casing, aguard secured'in the larger upper portion. of the cas--ing, a ball to enter said contracted lower portion of the casing andmovable in the erases upper larger portion thereof between said valveand guard.

6. A closure for a bottle comprising-a casing having its lower portioncylindrical and ol less diameter than its upper portion, longitudinalribs in the upper portion of the casing having their inner edgesapproximately in line with the inner face of the lower' contractedportieri oi the casing, a valve seat in the contracted lower portion ofthe casing, a valve normally disposed Within the contracted portion olthe casing, a ball normally disposed at the juncture of the larger andsmaller portions o1' the casing, and a guard secured in the largerportion el the casing.

7. A closure for a bottle comprising a casing adapted to :lit within theneck of a bottle, a valve seat attached to the casing near its lowerend, a valve to engage said seat, a series el ribs in the casingterminating at their lower ends above the valve, a guard secured withinthe upper portion of the casing and a ball witliin the casingintermediate of tbeV valve an d guard.

8. A closure for a bottle comprising a casing provided throughout aportion of its length with longitudinal ribs and lwith a valve seat atits lower end, a valve inthe casing below the longitudinal ribs andoo*-A operating with said seat, and a sphere" within the .casing abovethe valve and normally resting upon the top of the latter.
